Geode Dragons are closely related to Stone dragons. They are covered in a hard stone-like material as well as beautiful crystal. Their wings are entirely useless for flight, but they help attract mates. The dragons with the most brilliant and colorful crystals are more likely to mate.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

River is extremely agile and flexible for a Geode dragoness. It's not quite clear if this is due to magical influence on her egg or a malnourishment while she was a hatchling, keeping her crystals from hardening properly, yet the fact remains that she can move with an ease and grace otherwise not found in her breed. River has decided to make the most of it and has become a dancer. Even if she's incapable of including the classical air-dances and her movements are still slow and a bit sluggish compared to those of a Ridgewing or Silver, her skin glittering like gems and the sheer novelty of a dancing Geode are more than enough to draw a huge audience to all of her performances.
